[Freeswitch-users] Problem with SIP INVITE

Hi,

one of my ITSP is using Cisco 2811 (IOS 12.4) as H.323 to SIP gateway 
for SIP trunk to my Freeswitch.
I noticed that it sends INVITE message without SDP, and then Freeswitch 
terminates the call.
I tried using 3pcc parameter as "proxy" and as "true", but no avail.

Is this expected behavior, and could I fix it somehow?

Here's SIP trace:
